Area Forecast Discussion National Weather Service Wilmington NC 1220 PM EST Fri Mar 5 2021

SYNOPSIS. A dry cold front brings cooler air across the Carolinas Friday through the weekend, while low pressure passes southeast of the area with a few clouds possible through Saturday. Cooler air sticks around through Monday, before a warming trend carries through most of next week.

UPDATE. Biggest change with morning update was to drop dewpoints a bit and bump up winds, mainly gusts. Forecast soundings and 12Z data from MHX show 20-25 kt at the top of the mixed layer. Gusts 20 to 25 mph will be possible through midday or so. No other changes needed.

NEAR TERM /THROUGH SATURDAY/. A deepening upper trough just off the East Coast should provide below-normal temperatures for the Carolinas over the coming 36 hours. Cold advection has developed across the area this morning behind a front that moved through between midnight and 3 AM. Despite plenty of sunshine today, 850 mb temps will sink below 0C as north winds gust up to 20 mph. Highs are expected to reach 54-58 degrees, highest across the Pee Dee region. The incoming airmass is even drier than yesterday and forecast relative humidity is as low as 18 percent this afternoon.

Cirrus will begin to increase late in the day and should thicken into nearly solid overcast tonight. Surface low pressure developing across the northeastern Gulf of Mexico will remain well to our south tonight into Saturday. Given the cold airmass in place, Gulf moisture and weak isentropic lift on the 300K surface is all the way up near 15kft by the time it gets over the Carolinas. Given the considerable layer of dry air below the cloud base, I'm forecasting no precip for us. Clouds should begin to break Saturday afternoon with highs again reaching the 50s.

SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/. Trough deepens and moves offshore during the short term forecast period. Its associated surface low will drag out into the Atlantic, several hundred miles from the coast. With some of the low-level jet mixing down, look for northerly winds at 5-10mph with gusts up to 15mph on Sunday. Expect plentiful sunshine, but due to north- northwesterly flow, temperatures will be 10-12 degrees below normal for early March, including lows at or just below freezing.

LONG TERM /MONDAY THROUGH THURSDAY/. Strong trough pushes offshore by Monday, and some good springtime ridging begins. Surface high pressure from the mid-Atlantic quickly slides down into the Southeast, and provides one last cool day on Monday, with highs in the mid-to-upper 50s. Center of the high pushes offshore by Tuesday, where it will linger through the rest of the long term forecast period. Temperatures steadily increase everyday, with the 70s expected by Wednesday. Afternoon cumulus start to pop out as temperatures warm.

AVIATION /17Z FRIDAY THROUGH TUESDAY/. VFR. Slightly breezy north winds this afternoon will go calm tonight. High clouds move in this evening from the west, thickening overnight. Ceiling heights expected to remain 60 kft or higher, with ceilings less than 100 kft mostly across NE SC tomorrow.

Extended Outlook . VFR with mostly clear skies Saturday evening through Tuesday.

MARINE. Through Saturday . A dry cold front moved across the coastal waters between midnight and 3 AM. Winds rapidly increased behind this boundary and should blow at 15-20 kt with some higher gusts through the morning -- just below Small Craft Advisory criteria. Lighter winds are expected this afternoon a high pressure ridge begins to expand across the area. Low pressure is expected to develop across the northeastern Gulf of Mexico tonight but will remain too far south for any direct impacts on our weather. Northerly winds 10-15 kt tonight should diminish to less than 10 kt by Saturday afternoon as the low jumps across Florida and out into the open Atlantic.

Saturday Night through Tuesday . NNW flow at 5-10kts Saturday night increases to 15kts with gusts up to 20kts through Sunday night. Seas increase modestly from 1-2ft to 2ft. Winds veer more to the east on Monday, decreasing to 5-10kts and seas holding steady at 1-2ft. Wind direction becomes more variable through Tuesday.
